A Haitian musician wanted for killing his wife and her beau at a Bronx motel blew his brains out as police were about to move in on his Florida hideout.

US Marshals, NYPD detectives and local police tracked Joseph Kernizan, 42, to a home in North Miami, less than a half-mile from the Miami FBI building.

As they surrounded the single-family home where Kernizan was holed up just before 11 p.m. Tuesday, officers heard three shots.

A robot sent into the home relayed back video of the gruesome scene — Kernizan, dead of a self-inflicted gun wound, with a .380 caliber semiautomatic pistol at his side and two fully loaded AK-47 rifles in a duffel bag nearby.

Relatives were not surprised he met a violent end.

“I was worried this would happen. The family is just devastated,” said Marie Kernizan, 41, who was once married to Kernizan’s brother, Jean.

“Now all we can do is pray for his soul,” she said.

Kernizan — an Elmont, LI, resident who was prominent in the Haitian music scene in New York and Miami — was wanted for the jealousy-fueled slaying of his wife, Tracy Bennett, 38, and her boyfriend, Wayne Hamilton, 50.

Kernizan shot dead Hamilton, a Milwaukee resident, outside the Holiday Motel in Eastchester early Saturday. Then he chased Bennett around the hotel building on foot.
